If you want to communicate a sense of professionalism to your potential clients, you’ll need a business number. No arguing there. But what good is having a business phone number if the connection is bad? We always take call quality into consideration when doing our virtual phone system reviews.
So, for example, a softphone can combine a telephone conversation with text chat and screen sharing, which means a conversation between two employees can seamlessly add more participants, handle private text chats between those participants while the call is still going on, and extend to a collaboration session in which the group shares screens, documents, and data—no prep, no reserved lines, just button clicks. In the case of a CRM integration, the system could recognize the customer's phone number or some other identifier and automatically pull up that record for the technician or salesperson answering the call. It can even alert a manager to monitor the call if it's an especially important client.

The phrase ‘Your call is important to us’ is very overused and can sometimes come off as insincere. Instead your professional voicemail greeting should say something like ‘We appreciate your call and look forward to speaking with you soon.’
1. Thank Them or Apologize. The basic rule of thumb is that callers should hear one of two things when they first connect with your voicemail — either an apology for not being able to answer the call or a “thank you” for having called.
